First, you need to log in and go to Settings. Then, head to the section labeled Security & Privacy. Near the top is the Two-Factor Authentication tab. Click the Set up two-factor authentication link, enter your Twitch password, and type in your phone number.

You’ll receive a text message from Twitch with a verification code, so enter that on the website as soon as you get it. If you use Authy, you can use that instead of text messages.

That’s all it takes to get that extra layer of security for your Twitch account.

For viewers, this prevents people from gaining unauthorized access to your account and doing things that might get you banned from Twitch. For broadcasters, setting this up is even more important, as malicious people are likely to target well-known streamers and ruin their livelihood.
